A garage floor drain is a fantastic solution for managing water that overflows onto the floor. Moreover, it works well for mopping the floor and washing items inside the garage. Having a good garage floor drainage system helps keep the environment clean. Trench garage drains help keep water out of the garage.

Water soaking into your concrete or spilling onto the driveway is avoided with garage floor drains. The water runs off the concrete floor and down the drain as it is pitched into it.

This aids in keeping the driveway and garage surfaces dry and spotless. Water can collect on the concrete’s surface without a drain and soak in or need to be cleaned up. Setting up a floor drain made of concrete is not too difficult.

They resemble your shower’s drain exactly. The floor drain grate is visible, but beneath the floor are PVC pipes that direct water outdoors and away from your driveway.

Making a decision on the kind of floor drain you want is the first step. There are two main forms available: a long, narrow trench or a single drain with a round, square, or rectangular shape.

Trench garage drains are great for collecting and disposing of water at the door; they also prevent water from getting below the garage doors. A basic P-trap, like the one beneath most bathroom sinks, is to pipe many floor drains.

In addition to acting as a water seal, the U-shaped pipe beneath the drain allows material to accumulate. Other designs don’t require complex pipes; they only direct water out, much like a gutter.

Garage Floor Drain Types

You can install one of two primary types of garage floor drains.

Trench Garage Drains

Trench garage drains are rectangular, long, and thin. Hence, they are usually beside the doors or along the garage’s border. Proper placement allows them to catch overflowing water on the floor and prevent outside water from entering the garage. One of the main advantages of utilizing trench garage drains is this: in contrast to a conventional floor drain, they keep water out of the garage as well as within.

Additionally, trench drains can be very appealing. Because that’s the component you see, a lot hinges on the sort of grill you choose. The contemporary grates, with their angular perforations, are particularly cool. We also use them in the shower as well as the garage.

Usually, trench drains are sold in sections that must be constructed on location. They are therefore an extremely adaptable drain system. Some are well over ten feet long, while others are only a foot or two.

How to Make and Assemble Trench Drains

The drain and the grate are the two main components of a trench drain. Usually, the drain area is integrated into the concrete floor. The grate is attached to the drain once it is in position. For future drain cleaning, just remove the grates. Drains, like those in a conventional drain system, flow into pipes and out of the garage.

Pro Tip: Trench drains require more accuracy due to their length and are more costly than standard floor drains. For appropriate drainage, the drain must be flat and pitched into the pipe.

Trench drains are available in metal or concrete. Concrete with a stainless or galvanized grate is my preference. They are also robust and long-lasting. Due to the fact that automobiles and trucks will be traveling over the drain, you want it to be able to hold a lot of weight.

If the concrete floor in your garage has the proper pitch and the trench drain is placed correctly, you shouldn’t have any issues with water. For every drain system you install, this is crucial. They won’t work very well if the water doesn’t go into the drain.

Garage Floor Drain: Bell Trap Drains

Trench drains are considerably more complex than bell trap drains. They are merely simple floor drains in one single position, either square or circular. They are inexpensive, simple to install, and very functional.

A bell-shaped drain typically rests in the center of the floor or in the location where water needs to be drained. For instance, you would install the drain there if you were creating a wash area in your garage. They function exactly like a regular shower drain. Water enters the drain and exits via a pipe.
The floors of the new garage must all slope toward the bell trap drain if you want to install one. Doing this is more difficult than doing it trench-style. The floors need to pitch one way in order for trench drains to work.

Essential Features of Garage Floor Drains

Garage Floor Drain: Avoid Water Damage

In order to minimize potential water damage, garage floor drain systems—also referred to as floor drains for garages—are essential. Rainwater, snowmelt, and other types of spilled water are efficiently diverted by them, preventing them from standing and penetrating into the walls or concrete floor. Standing water can harm the structure significantly over time, necessitating costly repairs. You may prolong the life of your garage floor and prevent expensive water damage problems by directing the water into the drainage system.

Garage Floor Drain: Keeping Things Clean

Frequently, the garage serves as a workshop for auto maintenance or home remodeling projects. It’s also a typical location to keep outdoor equipment. As a result, different liquids, dirt, and debris may gather on the floor. Garage floor drains make cleaning easier by giving this kind of waste somewhere to go. This keeps your garage neat and organized, making it a more comfortable and useful area.

Garage Floor Drain: Handling Vehicle Fluids

For individuals who take pleasure in performing their own auto repairs or maintenance, the garage floor drain can be an invaluable tool. During these tasks, automotive fluids like brake fluid, antifreeze, or oil may spill or leak. These fluids can be effectively managed with the use of a garage floor drain, which keeps your workstation tidy and stops them from unintentionally getting into other parts of your house or yard.

Garage Floor Drain: Assuring Security

Moisture or oil can be the reason why the garage floor is slippery. The purpose of floor drain garage systems is to remove extra water and car fluids, which lowers the possibility of mishaps in the garage. All garage users will benefit from a safer atmosphere if the floor is always clean and dry.

Garage Floor Drainage System

Garage floor drainage systems are not limited to huge production facilities or outdoor spaces. They are also a necessary component of interior spaces, especially automobile garages, where messes are common.

Maintaining the cleanliness of the garage and removing any potential trip or fall hazards can be achieved with the aid of an adequate garage floor drainage system. Workers will also be able to swiftly clean up after a long day of work with the help of a drainage system. However, not every drainage system is created equal; therefore, you must exercise caution while choosing the finest and most efficient drainage system for a garage floor.

You want to take every precaution to safeguard your garage and the vehicles stored there. Installing the appropriate kind of garage floor drainage system is one of your options. Slot drain is among the best alternatives available, although there are plenty to choose from. It is safe, reasonably priced, and simple to maintain, and it complements any style beautifully.


Which Drain Is Ideal for a Garage Floor?

Because they are more durable, trench drains could be a preferable choice in some circumstances. The top of these drains has a grate covering linear channels. They work incredibly well to redirect a lot of water out of your garage. A trench drain system can also be formed using trench drains.

Can an Existing Garage Floor Have a Floor Drain Added to It?

Although drain systems aren’t usually pre-installed on the garage floor, garages need the same protection to keep the area dry and safe as residences and businesses do. Retrofit floor drains from Slot Drain are simple to install and can save damage worth thousands of dollars.

Can a Drain Be Installed on a Concrete Floor?

It is quite simple to retrofit a slot drain system into an existing concrete floor because of its shape and slope considerations. The subtle footprint of this system is perfect for worker safety and aesthetics if you’re not draining a lot of solid materials.

Do Drains on Floors Retain Water?

As you can see, floor drains, like sink drains in bathrooms, have those U-shaped P-trap pipes. The purpose of the U-shaped pipe is to contain water, which remains inside the pipe and stops sewage gases from rising via the drain.


A drain is a necessity in garages. Even though the door seal is effective when the door is closed, the garage door’s frequent opening and shutting means that the garage itself won’t always be shielded from the rain.

Rain and water from wash-down efforts must therefore find a way out, and if they remain within your garage, they will quickly cause the area to flood and smell bad.
